This happens occasionally to our company service trucks. Here is what we do when it does.
1. Get all the gasoline and or gasoline-diesel mix you can out of the tank.
That should leave only about 2 gallons of whatever in the tank.
2. Take 2 quarts of 30 wt. ND, no additives mineral oil and put in the tank.
Won't hurt the diesel and will add some lubricity to the gas/diesel mix.
3. Fill the tank completely full with diesel.
Go ahead and fill it up to reduce any gas diesel mix to a minimum
4. Put a piece of 5/16" fuel line hose on the fuel filter drain valve line.
You can leave this hose on when you are done later.
5. Put a container under the drain valve extension hose.
6. Open the fuel filter cannister yellow filter drain valve.
7. Turn the ignition key on, don't try to start it yet. Pump will run 10 sec
8 Wait for pure diesel to come out the hose and into the catch container.
9. When pure diesel comes out the drain hose close the drain valve.
10. Attempt to start, don't cycle the starter more than 30 seconds.
11. Wait 15 minutes between cycles, no more than 3 cycles.
12. If it doesn't start in 3, clean the head test ports and open them up.
Rear of drivers side, front of passenger side. You will have to move the
turbo intake hose and loosen AC compressor to get to them.
Get the test port area really clean, put some rags around the ports
13. Cycle the pump, let it time out, don't attempt to start the engine.
14. Diesel fuel, about a quart total should come out of the test ports.
15. When diesel fuel comes out put the head test port plugs back in.
Put the turbo hose, AC compressor and engine belt back in place.
16. The engine should start now but might smoke should clear up.
17. If it doesn't start now you have other problems. Check battery level.
You have to have enough power to get the engine to a min RPM for it
to start. With low batteries is can turn over but not get to min start
Hope this helps, 106
